Global trends and research hotspots in autophagy and tumor drug resistance: a bibliometric analysis.

Autophagy plays a crucial role in tumor drug resistance by enabling cancer cells to survive under stress conditions, including chemotherapy. It helps tumor cells maintain homeostasis, resist cell death, and contribute to therapy failure. This study analyzed the literature related to autophagy and tumor drug resistance based on the Web of Science Core Collection (WoSCC) database. The results revealed that there are 9284 relevant articles published to date, covering 103 countries and regions, with contributions from 5964 institutions and 37,240 researchers. The annual number of publications has steadily increased since 2004, especially after 2019, indicating the growing importance of autophagy in tumor drug resistance research. China leads globally in terms of publication output, accounting for nearly 50% of the total publications. Additionally, international collaboration and cross-country research have become increasingly prominent, particularly collaborations between China and countries like South Korea and Japan. Journal analysis showed that the International Journal of Molecular Sciences and Oncotarget are the most productive journals, while Autophagy stands out with a higher impact factor. Author, citation, and keyword analyses revealed research hotspots and future trends in the field of autophagy and tumor drug resistance, including chemotherapy resistance, cell death mechanisms, and immunotherapy. This study provides a systematic academic perspective for future research in the field of autophagy and tumor drug resistance and emphasizes the importance of strengthening international cooperation.
